alright i'm finally at a place financially where i can start buying parts to upgrade my car. but i need a plan first. I'm having a bit of trouble deciding which turbo to go with so i will tell you my goals and see what you guys have to say and why.

-power- i want to be able to make around 450+, whatever the max power i can get out of 100 octane from sunoco. thats the most expensive fuel i'm willing to pay for on a regular basis. and maybe just a couple times i'd want to see what the max power is and 1/4 mile time with race fuel.

-spool- i have nonseq twins at 12 psi right now on a pettit mild streetport 3mm seals. anything with less lag will seem like heaven to me. its going to be mostly street driven and a little autox every once in a while - I am very busy, not much time to go autox every weekend. but i'd like something at least with decent spool so i dont have to always stay above 3k rpms if i want to accelerate on the road.

basically i've really been looking into the 500r, i was told to look into the bnr twins and thats what i used to be interested in but looking at the dynos on zeroglabs i cant really see if there is that much of an advantage in the spool of the twins.

im gonna try to get either dee or ray to do this.

thanks for your input.

Take a look a broken09s car, he is running a 1.0 divided rear A/r 500R, great response good top end.

IMHO anything making 450whp+ is not going to have a whole lot of response below 3k. With a good twin setup or maybe a GT35/40 (or similar) 450whp could be made but the boost will be getting built in the 3-4k range.

Go natural, we are all addicted on oil



My best guess for your needs ? GT35r quick spool up, works well with your other equipment. I dont think 450 with it is possible but it will get you damm close with great spool up.

Next choice T78 a little lag for your application but it will put down over 400hp. Check the kit Sean at Aspec suggested, the work from his shop is outstanding.

Any way you go your going to have to invest some $$ on your fuel system and if 450 is your goal your going to have to replace the majority of it. Add another 1k to your budget.

My opinion is tainted on twins turbos since mine set me back a few years. I wanted to keep the cost down but after a set of BNR's and two other stockers I just gave in and went single.

Best of luck and dont be supprised if you blow away your budget.

I definately beg to differ. My car is as much fun to drive with plenty of low end response as it ever was with the twins. Add to that it's got gobs more power up top. With my current setup I'm seeing 14/15psi at right around 3400rpm but it's as if I have 7psi instantly. All this while making about 450whp at 15psi and supposedly there's now been a 20psi 500whp run unofficially with my car, All on Pump!

well i know that im going to have to replace almost everything since my car is mostly stock. i live with my parents and go to school and my job pays pretty well so i can spare a few bucks. i dont need to get exactly 450 or over, if i can get close that is good, but if i can get more that would be nice. water injection just seems like an extra hassle along with nitrous cooling, etc... so one of my big limiters i guess is 100 octane. now that i've decided on the 500r, i'll have to figure out what ecu, fuel system, etc...

already have an apexi fmic waiting to be installed, i have the two oil coolers from the r1 so i dont think i'll need to upgrade those.
in terms of radiator either koyo or griffin i guess. couldnt find too many comments about the griffin though.
have a greddy profec b spec 2
probably tial wg and bov. anyone want my greddy type r?
supra fuel pump will probably have to go.

PFC seems to be a good price, but if there are clear advantages of microtech or electromotive i mgiht be willing to spend more. either way gotta get rid of that pettit ecu.

broken what fuel setup are you running?

thanks for everyone's advice and help

I'm running dual intank supra pumps, 1600 secondarys, 850 primaries, A-Spec's fuel kit. As for ECU I'm running an LTX8S which I've been really happy with.
I had the PFC before and there were always some issues with hunting idle, missfires and so on, so I switched and have had no problems since.
Ignition I'm running 4 Crane coils and 2 amps.

There are plenty of turbos on the market that will get you that HP. T-78, T04S, T04R, 62-1 etc.. will get you to your goal. It all depends on what you want to spend.

yeah with a single that Strawberry 3rd gen will be one badass machine. You still have the blacked out wheels? Just a reminder that if you want 400's+ you are going to need so serious tires on the back of that.

yeah i still have the powdercoated stock wheels. right now i like the volk sf winning, lighter than the bbs i think. maybe michelin tires.

i think i want to spend around $15k, a little more if necessary, i dont want to half *** it.

I would suggest a Haltech E8 ECU for your car. It is incredibly capable and as soon as the new software comes out for it, you will have a self tune feature with it. And if you decide you want a Haltech then get a hold of me and I can set you up with the best price around on them.

The new Wolf 3D is supposed to be really nice too. I've heard nothing but good things about it.

And you mentioned a Griffin rad. I have been running one for quite a while and have had no issues with it. They work great and are WAY less expensive than a Koyo or Fluidyne. Top notch quality and killer customer service from them!
